The computer and other devices are able to communicate on the wireless network; however, you cannot setup or install the printer.

IMPORTANT! A computer connected via an Ethernet wired connection is different from a computer communicating over a wireless network. Hence, you must verify what other wireless devices are communicating with your router; e.g., any 802.11 g/b/n-equipped laptop, e-reader, smartphone, television, or other device.

Before you begin

If you receive this error at the time of initial setup and you are configuring the printer with a USB cable and the Lexmark Wireless Setup Utility, you will not be able to proceed until you know your router's configured security parameters.

SSID – NETWORK NAME

ENCRYPTION (NONE, WEP, WPA or WPA2)

User-assigned KEY or PASSPHRASE

See the checklist below for more information. You will obtain these values from your router. NOTE: Lexmark is not responsible for supplying these values.

Router Configuration Setting Checklist

Possible "Connection Failure" causes

Possible actions

Incorrect SSID (Network Name) selected

Note: You or someone that configured your network should know this name. Otherwise, a default service set identifier (SSID) or network name was provided by the router manufacturer.

Make sure you know if you are using WEP, WPA, or WPA2. See router's configuration web page or software configuration utility.

2007 Printer/All-In-One note: Only if using an older printer should you have to be concerned about TKIP vs. AES. It is suggested that the router/WSU setting (TKIP + AES) not be selected. Choose AES if using WPA2 and use TKIP is using WPA.

Warning! If you cannot resolve the correct key or passphrase, you will have to perform a complete restore/reset of the router's factory defaults, and you may have to reconfigure more than one wireless device on your network.

Other Router/Access Point Considerations

Note: For the following, you may have to contact or reference your router manufacturer's different support options.

DHCP (off)

Turn on the DHCP router setting. DHCP(off) will prevent the printer from obtaining an IP address.

Media Access Control (MAC) address filtering (on)

Note: Router naming convention for this feature varies.

This additional security measure on the router will have to include the printer's MAC/UAA 12-digit address be set to NOT BLOCKED.

Router running on the 5 GHz band

Make sure the router is using the 2.4 GHz band.

Other considerations

Action(s)

Firewall blocking communication

Firewalls or security software applications often create the majority of communication issues. They come in many forms:

Third party software firewall or security applications

BIOS or system firewalls

Router firewalls

Operating system firewalls

Create exceptions, or select Allow always if prompted with a balloon pop-up window that references some form of a (Lx...exe) process, or

Click here for firewall, processes, and port information which may help resolve this communication problem.

Contact your firewall manufacturer if you are unsure how to manage your firewall's allow/exceptions list.

Make sure the processes required by the printer to communicate are located in your firewall's exception list.

Also, locate the following processes and select "grant full access", or "grant always".

NOTE:Click here for more information on processes and executables utilized by the Inkjet Products. The <prefix> differs by printer model. For example, a Lexmark Pro205 will have a prefix of <eb>, so the name for the communications process will appear as Lxebcoms.exe.

IMPORTANT! Any blocked process will prevent communication to the printer. Contact your firewall manufacturer's technical support resources if you are unsure how to create exceptions or grant access to these processes.

Duplicate IP address –This condition is rare; however, if you are still able to ping the IP address with the printer powered off, then another device on your network has an identical IP address.

No, you cannot ping the IP address...

Possibilities may include the following:

The printer is on a different network from the computer.Action! See "No, you cannot ping the printer's network gateway address" below.

MAC filtering or other router setting is preventing success.Action! Consult with router manufacturer.

Interference or over saturation of wireless signals on a wireless local area network.Actions!

Adjust the router's access point radio channel; e.g., 1 instead of 6.

Look into bandwidth throttling, or other settings available to maximize signal. Important! Remember that certain router speed boost proprietary modes may not be compatible with the printer's wireless adapter.

Consult with router manufacturer.

Relocate printer, router, or other obstructions, which may be a source of interference or signal loss.

Timeout condition due to marginally acceptable wireless signal.Action! Relocate printer or adjust antenna position(s) on router or printer, if available.

Is the computer connected to the router with using a wirelessconnection?

If wired, does any other wireless device communicate with the router? Action: If no,your printer may be connected to a different network. Try to run the Wireless Setup Utility.Note: This is found under Lexmark Printer Home for 2009 products and is called Wireless Setup Assistant on a Macintosh computer.

Is the printer's IP gateway address the same as the router's IP address? It should be the same in most situations.

Explanation example: A printer's gateway address of 192.168.0.1 should be equal to the same gateway address found under the computer's ipconfig test.Moreover,this same address provides access to the router's web page.

NOTE: The connection scenarios depicted in this chart refer to a high-end All-In-One (AIO). However, the chart can be referenced for most wireless printers and AIOs. Minor behavior exceptions apply to older devices.

How to read this table

All communication scenarios below start with the printer turned off . However, it is important to understand that the Wi-Fi indicator light can go either direction.

Note: This is found under Lexmark Printer Home for 2009 products and is called Wireless Setup Assistant on a Macintosh computer.

Alternative: Wi-Fi protected setup (WPS) users can re-join the network using PBC or PIN methods. This can be initiated through the WSU, the router's configuration utilities, or the printer's "Wireless Settings" Menu.

9. Complete USB switch-over

This example: You are connected to a wireless network but you decide to operate only with a USB connection.

USB operation

Computer turned off.

Router turned off or unplugged.

Alternative: Original solid orange is obtained only by resetting your printer's network settings.

Table Key

AP – In most cases, the access point (AP) refers to the wireless (radio) portion of your router.

– Lost AP-to-printer radio communication due to router security settings, interference, distance, or placement

Post – This light-off condition refers to the printer or All-In-one (AIO) going to a Ready state. Therefore, the printer's wireless adapter is not yet Ready.

Configured/Connected – Proper network and security type was selected and proper security encryption key or password was properly entered to allow the printer to join the network.

Network dropped – Lost signal or communication with wireless router or access point (AP)

Ad-hoc – Refers to a wireless environment in which there is no AP. This would also be called a direct wireless computer-to-printer connection.

Remember, in order to successfully connect:

Proper network name (SSID)

Proper security type (WEP, WPA [TKIP]), or WPA2 (TKIP orAES)), and

Proper security key or passphrase must all be accurately selected or entered via the Wireless Setup Utility (WSU).

NOTE: The WSU equivalent in Macintosh environments is called the Wireless Setup Assistant (WSA). This Macintosh assistant can run from the installation CD.
